330389 ÷ 18 
We're looking to find how many times 18 goes into 330389.

Going ahead to step 1:
If we divide 3 by 18, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (3) from the dividend after 3, then repeat: 33 / 18

On to step 2:
The number 18 fits into 33 1 times, leaving a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 18 from 33 to get 15.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 18

Advancing to step 3:
If we divide 150 by 18, we get 8 and a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
The remainder is 6 after subtracting 144 from 150.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 18

Moving on to step 4:
The number 18 fits into 63 3 times, leaving a remainder of 9.
The next digit of our result is 3. 
Result so far: 183.0
The remainder is 9 after subtracting 54 from 63.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 18

Let's proceed to step 5:
18 goes into 98 5 times with a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 1835.0
The remainder is 8 after subtracting 90 from 98.
Append the next digit (9) from the dividend to 8 and continue with: 89 / 18

Step 6:
89 divided by 18 is 4 with a remainder of 17.
Record the quotient 4 as the next digit in the result. 
Result so far: 18354.0
The remainder is 17 after subtracting 72 from 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 7:
When dividing 170 by 18, we get 9 with a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 18354.9
If we subtract 162 from 170, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
18 goes into 80 4 times with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 18354.94
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
80 divided by 18 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 18354.944
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Our division results in 18354.944 with a remaining 0.0008.
